The Kennedy family feud continues.

Relatives of Mary Richardson Kennedy snubbed her husband, Robert Kennedy Jr., by not inviting him to a private memorial they organized today in New York, a source told The Post.

Instead, he’ll take their four children to Florida, according to another source.

Kennedy Jr. on Saturday delivered a self-serving eulogy at Mary’s funeral, disclaiming any blame for her suicide. Except for one sibling, none of Mary’s relatives attended the funeral.

Their alternate memorial is being held at the Standard Hotel downtown. It was planned by Mary’s siblings — her sister Joan works for Standard Hotel owner Andre Balazs — after a bitter falling out with Kennedy over her remains.

In Florida, the kids are likely to stay at their grandmother Ethel’s oceanfront home in Palm Beach, said a family friend.

“He was a terrible husband, but he’s a very good father,” still another friend said.

Hours before her Friday wake, Mary’s brother, lawyer Thomas Richardson, was in Westchester Supreme Court trying to stop Kennedy from claiming her body.

Mary’s family, upset over how she had been treated by the Kennedys over the years, also argued they should get the $4 million estate where she killed herself after spending years renovating it to make it eco-friendly.

The judge, in a closed hearing, ruled in favor of Robert, who was in the process of divorcing Mary and was trying to get full custody of Conor, 18, Kyra, 17, Finn, 15, and Aiden, 11.

Kennedy was awarded the house, as well as custody of the kids. Minutes after the ruling, Mary’s body was removed from the Medical Examiner’s Office and taken to a funeral home.

She was buried in a Cape Cod cemetery near the Kennedy’s Hyannis Port compound against the wishes of her siblings.

Mary, who battled alcoholism and depression, hanged herself at her Mount Kisco estate last week.

Only one of Mary’s siblings attended her funeral Saturday, attended by such celebrity friends as Susan Sarandon, Chevy Chase and Larry David.

Robert, who filed for divorce in 2010 ago after years of his rumored cheating, insisted, “I know I did everything I could to help her.”

He also said, “She really fought so hard. She had these demons, and she didn’t deserve it.”
